ID 4.1.1.106 DE fatty acid photodecarboxylase. CA a long-chain fatty acid + H(+) + hnu = a long-chain alkane + CO2. CC -!- This algal enzyme, characterized from the green algae Chlorella CC variabilis and Chlamydomonas reinhardtii, is dependent on blue light, CC which photooxidizes its FAD cofactor. CC -!- The enzyme acts on fatty acids in the range of C12 to C22, with a CC higher efficiency for C16 to C17 chains, and forms an alkane product CC that is one carbon shorter than the substrate. CC -!- The enzyme can also act on unsaturated fatty acids, forming the CC respective alkenes, but does not generate a new double bond. DR A8JHB7, FAP_CHLRE ; A0A248QE08, FAP_CHLVA ; //
